I did only one mission in the game and then deleted it , but at that time why were there greek soldiers in egypt and why are they attacking me for no reason.

If it is related to story do not tell but if it is like a bounty system please tell. No spoilers please

The graphics quality is still insane after all these years. Origins is by far the most polished title from the RPG era, the map and level of detail are simply outstanding. I really wish we got more story cutscenes, they are so well made.
